首发时间:2019-05-06
摘要:为满足半导体生产线多目标优化要求,对车间性能实现综合优化,在现有的动态调度方法研究基础上,以模糊理论为基础,结合Extendsim离散型仿真技术,以最大完工时间最小、最大拖期时间最小、总换模时间最小、平均流经时间最小、平均设备利用率最高等多个性能为优化目标,基于规则调度提出多因素复合规则调度模型,将车间加工实时情况收集并通过模糊逻辑决策进行处理分析,改变各调度规则的选择权重,从而调整为当前最佳调度规则。将其调度效果通过大量仿真实验与经典调度规则进行对比,并应用改进的TOPSIS法对多个方案进行评价,验证了该模型的可行性和有效性。

Simulation research on dynamic scheduling of semiconductor production based on composite rules
Abstract:In order to meet the multi-objective optimization requirements of semiconductor production lines, A multi-factor composite rule scheduling model based on the fuzzy logic theory and rule scheduling is proposed, in which the makespan, total tardiness, the mean flow time, total setup time and the utilization of equipment are considered. The real-time simulation of shop processing is collected and analyzed by fuzzy logic decision, modify the weight of each scheduling rule, then adjusts the scheduling rules. A large number of simulation experiments which is compared with the classical scheduling rules have been done, the evaluation results of the improved TOPSIS validate the feasibility and effectiveness of the model.
Keywords: simulation dynamic scheduling composite rules multi-objective optimization improved TOPSIS
